Available on back-order
Description
The generator triode GU-5B is designed to amplify power at frequencies up to 110 MHz in various radio engineering devices and to operate in high-frequency heating generators.
Cathode - tungsten thoriated carbide direct heating. Cooling - forced air.
Execution - glass-to-metal.

Payment & delivery
All shipments are carried out from our international warehouse in Dubai (UAE), as well as from our partners’ remote warehouses.
In Stock — items available in stock at the Dubai warehouse are dispatched within 5–10 business days after receiving 100% prepayment.
Remote Stock — items available at our partners’ remote warehouses are supplied within an average of 30–45 business days after receiving 100% prepayment.
Pre-Order — made-to-order products are manufactured and delivered within an average of 45–60 business days. Payment terms: 50% advance payment to start production, with the remaining 50% paid before dispatch from the Dubai warehouse after full readiness for shipment.
Returns & Changes (Restocking Fee)
For selected items, a RESTOCKING FEE of 10% may apply in case of return, order cancellation, or changes to the order specifications. This condition applies only to certain products and is confirmed at the order approval stage.
Warranty
All products are covered by a standard 6-month warranty.
Extended warranty is available upon request and is agreed individually; it may affect the final product price.
